Application

Convector heaters are generally installed in residential and administrative buildings, office settings and entrance halls, as well as storage facilities, changing rooms and other workplace areas. Individual models allow for installation in front of large glass walls or free-standing or wall mounted installation. Forced circulation models (fan-operated) are suitable for integration with low temperature systems.

Important features of lamellar heat-exchanger heaters include their low surface temperature and the option to select rounded corner models that are ideal for children’s rooms and other settings where increased safety is a concern.

Function

A “thermal screen” is created in front of a glass surface, which efectively separates the cold surface from the indoor environment. At the same time, air flow prevents condensation of air humidity on the surface. The vertical and horizontal distribution of temperatures within the heated space is even and favourable conditions are created to secure thermal comfort.

The air flow is comparable to heat transmission provided by traditional heating units mounted on walls under windows. As the temperature of the heater cover remains moderate during operation, it can never cause burn injuries. The entire heat output is transferred to the air streaming through the lamellar heat exchanger inside the heating body.

Operation

The heat output is controlled by a thermostatic head fitted onto the thermostatic valve of each heater. It responds to ambient temperature fluctuations and smoothly controls the flow of the heating fluid through the heat-exchanger.

Another advantage of the heaters lies in their ability to promptly respond to heating requirements, while the low volume of water in the heat-exchanger secures fast warming up to operating temperature.

Fan-operated convector heaters are controlled by a thermostat which regulates fan speed and the fl ow rate of the heating fluid. The heat output can be increased several-fold by forced convection, which is very useful during periods of extremely cold weather and it can be advantageously combined with low-temperature heating systems. All heater components are designed for safe 24V DC operation.

Vectair Self Standing ConvectorsBasic Information

Low-temperature heating systems

High-performance models with modern tangential 24V DC EC ventilators allow for integration with low temperature heating systems, making use of thermal pumps and other ecological heating sources.

Placement

Convector heaters are normally installed in front of windows to ensure optimum air circulation in front of the glass surface. Ideally, it is best if the unit occupies as much of the width of the window as practically possible. In addition, the height of each unit should be sized with regard to the character of the room as well as the height of the windowsill. Wall-mounted models can be anchored under the windowsill or to one of the inner walls.

Connecting in the heating system

Lamellar Al-Cu heat exchangers have aluminium lamellas pressed onto a copper pipe through which the heating medium flows. The pipe’s outlet and inlet are equipped with a connecting end with internal thread G1/2“.

We install a thermostatic valve fitted with an electrothermal actuator on the inlet of the lamellar heat exchanger. The actuator works in the opened/closed mode and controls the flow of the heating medium. It is not necessary to use a thermostatic valve if the temperature of the heating medium is controlled by the heating system (e.g. equithermal system). The way of regulation is to be determined by the designer of the heating and this shall be specified in the project documentation.

A return regulating screw connection shall be used for the outlet. This enables the incorporation of the convector into the heating system from the viewpoint of the hydraulic balancing. Based on the parameters of the screw connection used the designer determines the setting (corresponding to pressure loss at the fitting) and this value shall be specified in the project documentation.

Each exchanger is fitted with an air vent valve. When the heating system is connected and filled air bubbles remain caught in the upper part of the exchanger. These shall be let out through the air vent valve.

How to size the fan-operated convector heater

Placement of the convector

We always consider output and acoustic parameters of the convector taking into account the room’s nature - residential rooms, bedrooms, corridors, offices, theatres, hospital rooms, halls, presentation rooms and others. The convector shall comply with the requirement for thermal output at a selected temperature gradient, however at the same time the operation shall not disturb the user with excessive noise. The noise issue is regulated by the applicable standard, which defined permitted limits for individual types of rooms.

The output of the convector

The tables contain output data for thermal gradient 75/65/20°C, standardised output according to standard EN 442-2 and DIN 16 430 (Fan-operated convectors). This standard also defines the procedure for conversion to other thermal gradients. The second table presents a converted thermal gradient of 55/45/20°C and a fast approximate conversion for gradients of 90/70/20°C and 70/55/20°C.

• Convert the output to the required thermal gradient, check acoustic parameters.

• It is not a problem if the calculated output is higher than the required one - the automatic regulation functions from the lowest revs per the output that is equal to the current thermal loss in the room, the convector will not overheat, on the contrary it will function with less noise (it will achieve the required output at lower fan speed), the comfort temperature in the room will be achieved faster.

BMSConvector heaters equipped with EC fan technology in combination with a modern digital thermostat can easily be incorporated into building management systems (BMS). Communication with the superior system is either direct or via a thermostat with an output for KNX protocol communication. For other systems, it is possible to use protocol converters. BMS

Fan Convector Heaters AccessoriesSSFA, WMFA, SSFA, WMFA

Controls and a power supply need to be added to convectors to secure their correct function. The temperature in the room is assessed by a room thermostat

(RTD201, RTM201), which controls the fan’s revs and the flow of heating medium through the heat exchanger. The flow is controlled via an electrothermal actuator (Z-TS24), which opens or closes a thermostatic valve (Z-TD001, Z-TE001). We install the thermostatic valve at the inlet of the heat exchanger. In order to adjust the fl ow of the heating medium it is necessary to install and set a screw joint (Z-RD001, Z-RE001) at the exchanger’s outlet. The entire circuit functions on the basis of safe voltage of 24V DC, which is provided by a power supply 24V DC (DR, DRP), which shall be sized according to the number of installed convectors.

AcousticsWhen planning fan-operated convectors fan for residential rooms it is necessary to take into account the acoustic characteristics of the convector and the environment in which it will be used. It is necessary to design a convector complying with the applicable standard, which defines acoustic limits for individual environments. The values are prescribed by a national directive, which shall be observed - there may be differences in individual EU states. In general one can say that the upper limit for a daily room is 40 dB(A), the limit for rooms with night or relaxation regime is lowered to 30 dB(A), the limit for offices is 50 dB(A) and so on.

Different requirements for different rooms

• entrance halls, corridors, waiting rooms, foyers

• office space, administrative rooms

• residential rooms, public buildings, car showrooms, shops rooms for relaxation and rest (residential rooms, bedrooms)

Acoustic parameters in the catalogue

The acoustic parameters specified in the Vectair catalogue for individual products are valid for residential space “with standard equipment“. This means that the room is equipped in the standard way. Curtains, drapes, possibly Venetian blinds are fitted at windows, the floor or a part thereof is covered with a carpet, furniture is present. All these elements absorb or dissipate acoustic waves in the room.

Changes and the influence on acoustic pressure

The type of space for which we design the Vectair fan operated convectors has fundamental influence on the total noise level of the environment connected with its operation. Reverberation occurs, resounding waves take relatively long time to die down (they are not absorbed), they mutually influence and magnify each other. The total level of acoustic pressure can be increased by as much as 3-6 dB(A).

• The undesirable effect of acoustic pressure is increased by convectors installed near corners or under ceiling without cover.

• Rooms with minimalistic equipment without dampening elements and with a resounding floor without any cover have signifi cant impact on the worsening of the total acoustics of the space. From the viewpoint of the assessment of the acoustic limit the infl uence of the room (with or without equipment) is not taken into consideration, the regulation assesses the fitness of the room in its current condition (at the time of measuring). In practice an empty room may be measured. Therefore the designer of the heating system shall take into account all possible variants of installation into a given space or he/she may draw the investor’s attention to available solutions using an alternative (more powerful, less noisy) convector in bespoke cases.

• It is important to take into consideration acoustic parameters when installing more convector in a single room.

Acoustic pressures of individual convectors mutually influence one another, resulting in an increase of the total noise level. It all depends on the type of the room, the characteristics of the convector and the distance between individual bodies. It is necessary to design heating bodies with a sufficiently low level of acoustic pressure at the selected output and the revs of the fan.

The designer shall take into account all aspects of the room in which the convector is to be installed.(i.e. the equipment, dampening elements, floating or double layer floor etc.)

Measuring the acoustic pressure

The measuring took place in semi-anechoic chamber. The acoustic chamber complies with ISO 3745 standard in terms of frequency range 100 Hz to 20 kHz. An accurate Brüel and Kjaer phonometer was used for measuring which complies with 1st category of measuring accuracy. The measuring methodology is based on the recommendati-ons specifi ed in the Methodology manual for noise measuring and assessment in non-working environment. Sensing device was placed diagonally one meter above the convector and 1 meter from the convector into the room. The values were adjusted to the conditions of a room with “standard equipment“ with standard reverberation and reflectance.
